Abstract
The utility model discloses an electromagnetic relay shell, the shoulder hole that supplies the terminal to stretch out is seted up on the surface of shell, the terminal reaches cascaded surface between the lateral wall of shoulder hole is equipped with the highest region of level, minimum region and transition region, transition region connects the highest region reaches minimum region, so that the cascaded surface centers on around the terminal. The utility model discloses electromagnetic relay shell has a little and to glue conveniently, is convenient for glue uniform flow to the terminal around, effectively improves the advantage of the gas tightness of shell.
Description
Technical field
The utility model relates to a kind of electromagnetic relay shell, particularly relates to a kind of electromagnetic relay shell.
Background technology
Relay application is in various environment, when relay application just requires that in the environment with fuel gas it has good sealing property, this be due to relay operationally, when inner movable contact spring and static contact activity, likely produce electric arc, and once the shell of relay can not isolate extraneous fuel gas effectively, fuel gas just can be made to enter inside, thus the accident that sets off an explosion.
Existing high-current relay stretches out outside relay1 case due to terminal, although coordinating between shell with terminal is very tight, but still there is trickle space between shell and terminal, therefore, need to carry out a glue sealing to the space between shell and terminal.But because the gap between the sidewall of shell and terminal is less, glue has again certain viscosity, and flowing slowly, does not even flow to terminal surrounding completely and just solidified, thus cause a glue weak effect, the air-tightness of shell finally can be made very poor.
Utility model content
It is convenient that the purpose of this utility model is to provide a kind of some glue, is convenient to around glue Uniform Flow to terminal, effectively improves the bubble-tight electromagnetic relay shell of shell.
To achieve these goals, the surface of the electromagnetic relay shell that the utility model provides offers the shoulder hole stretched out for terminal, cascaded surface between the sidewall of described terminal and described shoulder hole is provided with level height highest zone, lowermost extent and transitional region, described transitional region connects described highest zone and described lowermost extent, is centered around around described terminal to make described cascaded surface.
Compared with prior art, because the utility model by arranging highest zone on cascaded surface, lowermost extent and two transitional regions, regional is utilized to have different level heights, thus when glue, only need glue be injected on cascaded surface, glue just can flow to lowermost extent from highest zone automatically, need not manually be applied to around terminal, can make glue rapid Cover around terminal on the one hand, point glue is quick and convenient, on the other hand due to glue energy automatic flowing, therefore gap less between side wall of outer shell and terminal also can rapid osmotic be entered, thus reach uniform fold, the gap avoiding some narrow does not have glue sealing, cause a situation for glue weak effect, the sealing of effective raising electromagnetic relay.
Preferably, on described cascaded surface, the region that between the sidewall of described terminal and described shoulder hole, width is larger is highest zone, and the region that between described terminal and the sidewall of shoulder hole, width is less is transitional region, and the region that transitional region described in two crosses downwards is lowermost extent.By region less for width between described terminal and the sidewall of shoulder hole is set to transitional region, glue can be made automatically to flow through transitional region, and flow to lowermost extent, thus realize glue and be covered in described cascaded surface completely, guarantee point glue effect.
Preferably, described transitional region is squint plane or arcwall face.

Embodiment
For describing technology contents of the present utility model, structural feature, the effect that realizes in detail, accompanying drawing is coordinated to be explained in detail below in conjunction with execution mode.
As shown in Figure 1, Figure 2 and Figure 3, the surface of the utility model electromagnetic relay shell 100 offers the shoulder hole 1 stretched out for terminal 200, the upper hole 1a and lower opening 1b of described shoulder hole 1 is all square, the cross section of described terminal 200 is square in what coordinate with lower opening, cascaded surface 2 between four sides 201 of described terminal 200 and four sidewalls 11 of described shoulder hole 1 is divided into four regions, be provided with three kinds of regions that level height is different in these four regions, be respectively highest zone 21, lowermost extent 22 and two transitional regions 23; On described cascaded surface 2, two regions that between the side 201 that described terminal 200 liang is adjacent and the sidewall 11 of described shoulder hole 1, width is larger consist of highest zone 21, two regions that between the another two adjacent sides 201 of described terminal 200 and the sidewall 11 of shoulder hole 1, width is less are transitional region 23, and the region that described in two, transitional region 23 crosses downwards is lowermost extent 22.By region less for width between described terminal 200 and the sidewall 11 of shoulder hole 1 is set to transitional region 23, glue can be made automatically to flow through transitional region 23, and flow to lowermost extent 22, thus realize glue and be covered in described cascaded surface 2 completely, guarantee point glue effect.Described transitional region 23 is squint plane, and the level height of squint plane reduces gradually, and transitional region 23 described in two connects described highest zone 21 and described lowermost extent 22, is centered around described terminal 200 around to make whole described cascaded surface 2.Transitional region 23 described in the utility model also can be arcwall face.
During point glue, glue is flow in described highest zone 21, glue flows from highest zone 21 to lowermost extent 22 under gravity, through described transitional region 23, because transitional region 23 is squint plane, even if the width between described terminal 200 and the sidewall 11 of described shoulder hole 1 is narrower, glue still can automatically flow through described transitional region 23 rapidly and cover described transitional region 23, the described lowermost extent 22 of final arrival, finally, glue can be covered in described terminal 200 surrounding and fill the upper hole of described shoulder hole 1, realizes the sealing to shell.
Compared with prior art, because the utility model by arranging highest zone 21 on cascaded surface 2, lowermost extent 22 and two transitional regions 23, regional is utilized to have different level heights, thus when glue, only glue need be injected in described highest zone 21, glue just can flow to described lowermost extent 22 from described highest zone 21 automatically, without the need to being manually applied to terminal 200 around, can make glue rapid Cover around terminal on the one hand, point glue is quick and convenient, on the other hand due to glue energy automatic flowing, therefore gap less between the sidewall 11 of described shoulder hole 1 and the side 201 of terminal 200 also can rapid osmotic be entered, thus reach uniform fold, the gap avoiding some narrow does not have glue sealing, cause a situation for glue weak effect, the sealing of effective raising electromagnetic relay.
Above disclosedly be only preferred embodiments of the present utility model, certainly can not limit the interest field of the utility model with this, therefore according to the equivalent variations that the utility model claim is done, still belong to the scope that the utility model is contained.
